Grapefruit dissolves well in olive oil but the lemon juice produce strong emulsion. When I drink it I feel that the olive oil is up and the lemon juice is down. But it does not matter. I drink about 400 ml ~ ( 200 ml OO (Olive-Oil) and 200 ml lemon juice ) in 5 sec maximum and then lie down immediately. I dont have problems with them(only in the morning I feel like vomiting but I think its Its because not all of the OO (Olive-Oil) is absorbed) Warm them up before drinking them. The mixture should not be too cool or too hot. Body temperature is perfect. I have never tried to mix them with coke and I dont know what is the point of doing this. Try to think of your liver when you drink them. Do not think of their taste. The taste of espom salt is worse than the taste of the olive oil. I have read the coke flush but I don't want to do it. I don't drink coke and any artificial "juices" or soft drinks. Try to do the flush without coke. May be you drank too much liquid ( OO (Olive-Oil) + lemon + coke > OO + lemon ? ) And its important to have empty stomach at 22:00. So stop drinking any liquids after 20:00 ( second ES dose).
